Understanding Hair Loss
Androgenic alopecia is the scientific name for the genetic predisposition in both men and women for pattern baldness. Genetic hair loss in men is often referred to as Male Pattern Baldness (MPB) and is the cause of thinning hair in over 95% of patients who seek treatment. MPB occurs in predictable stages, and is relentlessly progressive. Usually the earlier in life hair loss begins the more advanced the pattern will ultimately become.
In MPB the hairs on the top of the scalp have a genetic sensitivity to the male hormone testosterone (DHT). The hairs on the sides and back of the scalp do not possess this sensitivity to DHT and therefore are not affected. For this reason hairs removed from the sides and the back (Donor Hair) will maintain their genetic predisposition when transplanted and continue to grow when moved to the top of the scalp where hair loss has occurred.
Hair loss in females is less predictable. The hair loss tends to be more diffuse creating a more generalized thinning effect throughout the entire scalp. Fewer medical and surgical options are available for these patients.
